This hook-like portion 5 provides a resistance against accidental withdrawal of the v-shaped portion from the aperture 7 in the structure 6. 45 It also has the tab-like end 8 bearing against the structure 6 to prevent tipping of the device relative to the structure when attached. The tab 8 is also useful in connection with pulling the device free from the supporting structure 6. 60 The conduit-holding portion 1 is shaped to permit. entrance and withdrawal of the conduit 2 (shown in dotted lines in Figure 1) before or after the device is attached and, therefore, permits removal of the conduit without unnecesu sarily removing this fastening devi
